President Obama’s last days in office could see a flurry of new executive orders and last-minute regulations, but many of his plans that would require approval by Congress are dead thanks to Donald Trump’s election.

The bad news for the president includes the fate of his Supreme Court nomination and new environmental regulations, which one Republican Capitol Hill aide described as “kaput.”

And as for the Trans-Pacific Partnership, a trade deal that is strongly opposed by Trump, New York Sen. Charles Schumer admitted to union leaders on Thursday that it will never pass.

Obama is likely to turn instead to other avenues of power for lame-duck presidents.

He’ll likely continue commuting the sentences of prisoners — which he did at a record pace — and will likely issue some pardons, according to reports.

He also could issue “midnight” regulations, including approving new rules on such issues as renewable fuels and methane, the Washington Times reported.

Obama has already become known for creating policy through executive orders as he did with immigration.

He could follow his predecessors and issue late orders. It was unclear if he would match George W. Bush, who issued 11 in his final days in office, or Bill Clinton’s 22, because they could be undone by Trump when he enters the White House.

There is legislation the lame-duck president will be able to pass. That includes a “housekeeping” bill necessary to keep the government funded in the beginning of December and perhaps a law that would further Obama’s State of the Union pledge to eradicate cancer via a “moonshot” effort headed by Vice President Joe Biden.

In an Oval Office meeting Thursday between the outgoing and incoming presidents, Obama seemed to concede that he is now focusing on handing over the keys of his residence for the last eight years to his successor.

“My number one priority in the coming two months is to try to facilitate a transition that ensures our president-elect is successful,” Obama told reporters as Trump listened in the chair next to him.

White House press secretary Josh Earnest appeared to be more optimistic.

“The president and his team use every moment remaining to do the work of the American people and to effectively implement the kinds of policies President Obama has prioritized,” he said.

Earnest said Obama would be focused on ObamaCare sign-ups, which are currently open.

But a key aide on Capitol Hill told The Post that Obama won’t be able to clear out the prisoner detention center at the Guantanamo Bay Naval Base in Cuba, where detainees in the war on terror have been held since the George W. Bush administration.

In his first campaign for the presidency in 2008, Obama pledged to close the detention center in his first year in office.
